A new research, light pollution showed that its color and intensity have complex and unpredictable effects on animals’ vision. Insects we all know it comes to light, but artificial lighting may have more uncertain consequences for species that rely on night vision for a living.

To explore these effects University of Exeter researchers tested more than 20 light species on lepidoptera and the birds that eat them. The research revealed that some types of light improve the snake caterpillar’s vision, while others impair it. The sight of the lepidoptera-eating birds was positively affected by all types of light.

But it’s hard to know how these modern light sources affect the vision of other animals. Lepidoptera eyes are sensitive to blue, green and ultraviolet; this way they can find flowers like bees, but only at very low light levels.” he said.

Troscianko continued: Light pollution can make it difficult for these species to locate and pollinate flowers and find camouflage spots to protect them from predators. Birds, on the other hand, have a more solid vision; so artificial light makes them easier to hunt. ”
